high, about 1-1.5 n1m - thick at the basal portion, gradually taper- 

 ing above ; branches not constricted at base, thickish, much 

 wrinkled after drying. Plant when young abundantly provided 

 with elongated and flaccid branches, but becoming barren, when 

 old, dropping off most of them. Ramelli are sparingly present ; 

 a few of them arise on all sides on the apical portion of young 

 ramuli. They taper toward both ends, short, 375-475 // long, 

 slightly incurved, round at apex, poorly provided with a single 

 row of a few roundish genicular cellules which are mostly present 

 at the external side of nodes, or often wanting. Their articulations 

 are slightly constricted at nodes and subaequal to or little longer 

 than broad. The cortical layer surrounding the central axis is 

 thick, and it is internally composed of a few layers of larger 

 oblong cells which become gradually smaller outward. Fertile 

 ramelli bearing tetraspores and antheridia are densely tufted and 

 antheridial ramelli form small cushion-like whitish flecks alono- the 



o 



inner side of branches and mostly in axils. Colour dull pinkish 

 or brickish red, becoming paler in drying. Substance thick 

 and soft-cartilaginous. In drying, the thicker portion of frond 

 becomes very much wrinkled ; plant becomes brittle, and does not 

 adhere to paper.
